Abstract

Se presenta un sistema de antenas para su uso en transmision y/o recepcion de por lo menos dos senales, por lo que una primera de dichas senales es generada en una primera banda de frecuencia de operador por un primer operador (1760A) y una segunda de dichas senales es generada en una segunda banda de frecuencia de operador por un segundo operador (1760B). El sistema de antenas comprende un ensamble de antenas (702) con un angulo ajustable de inclinacion electrica, e incluye varios elementos de antenas (E1-En) para transmitir y/o recibir dichas senales, en donde los elementos de antena son montados en un portador de antenas y colocados en por lo menos dos subconjuntos (700A, 700B, 7000), cada subconjunto incluyendo uno o varios de estos elementos. Se proporcionan dispositivos de control (750) para controlar electricamente la fase de las senales transmitidas y/o recibidas por dicho ensamble de antenas, controlando de esta forma el angulo de inclinacion electrica de dicho ensamble de antenas. El sistema incluye dispositivos combinadores (730, 740) para sistema que dicho ensamble de antenas transmita y/o reciba sustancialmente simultaneamente una primera de dichas senales en un primer angulo de inclinacion electrica y una segunda de dichas senales en un segundo angulo de inclinacion electrica.
